ES82 Argon Purged?

Just received my 4.7mm eyepiece (super cool looking box by the way, I will have to post a picture) and ...
It says
4.7 and just below that it says
"82d SERIES FULLY MULTI-COATED"
and down below that it says
"ARGON-PURGED WATERPROOF"
with the little Ar sticker
Hmmm, what's up with this?

At least, that's what I heard.
That makes a lot of sense from the standpoint of manufacturing costs.

I like the idea of the Argon version.
By the way here are 2 pictures of the new box:

They were 2meg each and so couldn't upload them here.

The box clearly says N2, but the EP says Argon, with the symbol Ar on it.
I triple checked the EP, wondering if it was a 68 degree series, the wrong size, etc. I am going to make sure the serial number matches the box and check with ES to be sure this is legit, but my inclination is to think they are switching processes in manufacturing, moving to Argon for their 82 series... At least I hope that is the case.
In the meantime, I took it out for what I thought would be a quick spin this evening. 2 hours later....

I just received my ES 82° 11mm. The box (new style, apparently, with the three-flap opening and magnetic closure) sticker says N2. The eyepiece printing says "Nitrogen Purged Waterproof."
But, inset into a circular space on the eyepiece it has a round, green sticker marked "Ar."
So it's possible I have an early Argon-purged version, before ES updated the printing on the eyepiece?

I won't entirely fault ES sales/marketing on this 'messy' evolution. No doubt the money saved by NOT transitioning from old to new, and simply disposing of the old at a loss, would otherwise have found its way into the consumer pricing. Certainly into lower margins for themselves, at the least.
It would be nice, however, if a paper insert explaining the transition were added... or at least something featured prominently on their website? That latter bit doesn't cost much, at all. Last check, they were still touting the ES82 Nitrogen purge product line. No mention of a transition to Ar from N2. They must realize this is a point of confusion for consumers.
If it keeps the cost down, they can remove all lettering (except the mm designation), put it in a plain brown box with the gas used for purging written on it with a sharpie. If the net result is still the same, I'd be satisfied. However, I will admit that the box and the EP's are handsome as is. At some point, I guess all the labeling will be realigned.
In the meantime, perhaps some 'collector's items' are being made, with the N2 lettered, Ar purged rares? ;-)

Since rubber seals seem to last longer with Argon inside, I believe they are in the process of converting all N2 purged eyepieces to Argon.
At least, that's what I heard.
That makes a lot of sense from the standpoint of manufacturing costs.
Also from the 5 year extended warranty standpoint if the rubber seals vs Nitrogen don't stand up to the 5 year test of time.

Oh great!Since rubber seals seem to last longer with Argon inside, I believe they are in the process of converting all N2 purged eyepieces to Argon.
I bought my nitrogen purged versions last year.
Now I have to upgrade?

I am new, here... but as a long time member at DPreview.com, which attracts a high percentage of 'gear heads', things like this would have a way of taking on a life of its own and before you know it, a myth would be born.
I'm not disrepecting DPR, its members, or gear-heads. I am 'one of them' so I feel entitled to throw rocks in my own house. It's just an observation based on my experiences. =:-O
I'm sure CN is host to a more rational crowd, given to a greater degree of objectivity. ;-)
...now, I'm off to google "ES N2 vs Ar comparisons", hoping to find someone that concludes that Ar offers superior 'something'. :-)

It is also my understanding that the newer style boxes (at that time) were labeled N2.
All that really matters (if I can say that as I don't think the difference between N2 and Ar are of any major significance) is what label is on the eyepiece.
If the label says it's Ar then it's Ar purged.

All of mine are N2 purged too, but I wouldn't worry about it. Nitrogen preserves tires just fine, it will also certainly be friendly to the glass, metal and rubber seals that make up ES eyepieces. It has worked fine for fog proofing rifle scopes, spotting scopes and waterproof binoculars too.

+1 to that.

all this being said here though, i'll throw in my knowledge from the glass industry i work in on gas filled glass units (what this bassically is)
nitrogen is a major component of our normal air on the planet.
http://en.wikipedia....sphere_of_Earth
saying something is N2 purged without stating percentages is as good as telling me its filled with plain old AIR
Argon on the other hand is known to be a good insulating gas. when an insulated window is filled with 90/10 (Ar/air) mix there a measurable insulating factor made on a sealed glass unit. there are other gasses that perform even better but they are more rare, more expensive and when you factor in that gasses will almost always escape over time and eventually the end result is it does not matter IMO and if anything Ar filled is going to benefit more than N2 anyways.
sorry i just see it sort of a marketing ploy i suppose, not knocking ES by any means though their eyepieces are great and i own one already.
